United States Patent RECORDING AND COUNTING DEVICE John Dumitriu, 806 Albert Road, Windsor, Ontario, Canada Filed Jan. 13, 1959, Ser. No. 786,526

Claims. (Cl. 197-57) This application relates to recording and counting devices and more particularly to devices used for recording How- -ever, asa recording and counting device, it obviously strokes, for example.

An object of the present invention is to provide a recording and counting device of rather small size which can be operated manually for recording the number of turns or plays of a roulette wheel or of some other game and the number that comes up on each play.

. For an understanding of the device, reference should be had to the appended drawings which disclose a preferred embodiment of the same.

In these drawings:

Fig. 1 is a top plan view of the device.

Fig. 2 is a top plan view with the cover removed.

Fig. 3 is a section view, as if on line 33 of Fig. 2.

Fig. 4 is a section view as if on line 44 of Fig. 2.

Fig. 5 is a section view as if on line 5-5 of Fig. 2.

' 'Fig. 6 is a section view as if on line 66 of Fig. 2.

Fig. Fig.

7 is a section view as if on line 77 of Fig. 2. 8 is an enlarged fragmentary view of the printing belt, anvil plate, and end view of the hammer.

' It will be understood that in each view certain parts are omitted for purposes of clarity.

The device comprises an open top box 10 having a cover 11 which is removable but which is generally left in place except when it is desired to obtain access to the interior. Normally the cover 11 is closed.

Selection operation Extending longitudinally of the device and near the front wall 12 is an endless chain 14 (see Fig. 2) mounted on sprockets 15, 16 suitably supported in the device with sprocket 16 being on a shaft 17 having a beveled gear 18 meshing with a beveled gear 19 keyed to a longitudinally extending operating shaft 21.

j spool 24 suitably mounted in the device.

The latter has its left end keyed to a spool 22 over which passes an endless rubber belt 23 which also passes over another Chain 14 and v,shaft 21 extend longitudinally of the device whereas belt 23 extends transversely.

. Above the cover 11 and thus exposed is a selector or slide 26 which is pivotally mounted on a key 27 fitted 1 into a link of the chain 14 whereby as the selector 26 is moved manually left and right along the forward part of the upper wall of the cover of the device, it may cause the chain14 to shift 'left and right, rotating shaft 17, gear 18, gear 19, shaft 21,-and spools 22 and 24, and

thus move belt 23 in its transverse path.

The inside surface of the belt'is formed with raised 'ice Printing The slider 26 is in the form of a bell crank and has a depending part 31 (see Figs. 3-5) in position to engage the upper longitudinally extending part of an operating bar 32, the latter being pivoted at 33 and having an operating lever 34 connected at 35 to another lever 36 pivotally mounted at 37 and connected at 38 to a rod 39 whose upper end is connected at 40 to a hammer 41 (see Fig. 8). The hammer is formed of two spaced, identical hammer parts which are pivoted at 42 and are interconnected by a hammer end 43 equipped with a locating pin 44 for cooperating with a perforated hole 45 in the belt 23 positioned to be engaged and impacted by the hammer end 43 of the hammer 41. Thus, when the selector or slider 26, after having been moved left and right to a selected point or number on the keyboard 30, is then moved downward manually, through the action of the parts 313234-36394041, the hammer end 43 is caused to strike downward on the upper surface of the belt 23. This is printing operation.

Paper feed Positioned under the belt is an anvil plate 46 (see Fig. 5) on one end of which is an inking roller 47 for inking the inside surface of the belt 23 as the latter is moved on its spools 22-24 by the sliding of the selector 26. Between such anvil plate 46 and the lower surface of the belt 23 is a paper tape 50. The tape passes between the two spaced parts of the hammer and beneath the hammer end 43. Its trailing end is wound upon a spool 51 and its leading end is adapted to be wound up on proper feed motion of the paper tape on a spool 52. The path of movement of the paper tape is longitudinal and is thus transverse of the path of movement of the belt 23.

Connected to hammer 41 at 53 is a longitudinally extending pawl 54 whose end 55 is formed for engagement with the teeth of a ratchet wheel 56. Mounted on the same axle as the wheel 56 is a roller 57 (see Figs. 2 and 4). The roller 57 is in frictional engagement with a pressure roller 58 which is carried by one end of a lever 59, pivoted at 60, and whose other end is held by a spring 61.

The pressure roller 53 is fitted inside spool 52 to press against the leading end of the paper tape as itis wound on the hub of such spool. Thus, rocking of the hammer 41 will cause reciprocation of the pawl 54, step by step rotation of the ratchet 56 and its roller 57, and thus step by step rotation of roller 58 pressing against the roll of paper, and step by step winding up of the paper on the hub of spool 52. This action takes place when the hammer is released by release of pressure on the slider 26 and is caused by a spring 62which tends to rock the hammer 41 counterclockwise when viewed in Fig. 3, such spring being overcome by downward pressure on the slider 26 for printing, and such spring serving to lift the hammer from the rubber belt and at the same time causing the pawl 54 to move and cause the feeding of'the paper tape 50 one space at a time. This is the paper feed operation.

The paper tape is exposed through a cutout 63 in th cover 11. Thus, the numbers printed on the upper surface of the tape, by the action of the hammer 41 on the rubber belt 23 in response to the successivesliding and pressing down on the selector 26, will be exposed through the openings 63.

On the same shaft with ratchet 56, but well behind it,

' is a counter 66 exposed through a window 67 in the cover 11. The counter is of any conventional electrical or mechanical type which counts, in response to the angular movement of the shaft, the number of actuations of the .next successive series of plays.

paper tape'59 to the number of times that the device is operated, 'there is provided on the same shaft with the ratchet wheel 56, but immediately behind it, a pinion 69 larger than ratchet 56 and meshing with a pinion 70, the

latter having .a hub '72 slidably mounted upon a shaft 73 and also'having a pinion 71 larger than pinion 70. Immediately above the pinion 71 and extending longitudinally is a number bar 76 whose lower surfaceis 'formed as a rack .77 meshing with the pinion 71 and whose upper surface has a series of numbers corresponding to the number of plays, in this case numbers 1 to 15. The number of plays are exposed through a transparent window 78 j.(see Fig. 1) as the number bar is -moved from right to left due to successive manipulations of the -selector;26 for printing. The operative connection bea tween the selector 26 and the number bar 76 is established through the following parts: selector 26, parts 31-32-'-3436394041, pawl 55, ratchet 56, pinions 69, 70 and 71 and rack 77. Thus, the manpulation of the slider 26 for printing, simultaneously causes movement to the left of the number bar 76 in synchronism with the printing operation.

' Reset for number of plays indicator When a series of plays have been completed (e.g. fifteen plays) the number bar 76'is reset to indicate the The reset mechanism consists of a push button or knob 81 which is connected .to a bell crank 82 that is pivotally mounted at 83. The

.lower end of the bell crank is connected to the hub 72 of the pinion 71, there being a pin and slot connection at 84 for keying the hub 72 on the shaft 73, and there also being .asmall coiled compression spring 85 (shown dotted) inside the hub. When button 81 is pushed down it moves hub 72 to the right (as viewed in Fig. 7) overcoming the small spring 85 within it to disengage pinion 71 from the rack 77 of number bar 76. Then a coil spring 86 connected to the right end of the number bar at a pin 87 pulls the number bar 76 to the right, away from the window 78, to zero position.

Thereafter, when button 81 is released the coil spring 85 within the hub 72 on shaft 73 pushes the pinion 71 again into engagement with the rack 77 of number bar 76 so that the number bar is now connected again, through the pinions 71, 70, 69, ratchet 56, pawl 55, and hammer 41, to selector 26. Hence, the number bar is ready to be moved to the left to again register the number of plays of the selector 26.

Summary It will be observed from the foregoing that there has here been disclosed a simple and convenient assembly of parts which can be manipulated to print a series of numbers as selected on a paper tape, and to count and indicate the number of plays or selections that have been made (on the counter bar 76) in any one series of selections, and also to count the total number of selections (on thecounter 66) reflected .by the total number of manipulations of the selector 26.

It will also be observed ,that a convenient compact assembly is shown, whereby four. major parts are placed in longitudinally extending parallel relation in the casing: namely, the sprocketchain 14, the keyboard 30, the operating-shaft 21, and the paper tape 50. These parts nane-e17"- e the selector 26, and thus correlating the printings onthe H iarenbridgedby anansverselvemndingnrinting belt.

with a hammer at the point ,of intersection of the printing belt and the paper tape, and are actuated, through a linkage, by the selector 26, which is moved longitudinally along the keyboard 30' and which is pressed downwardly for printing.
